No, you cannot nap in O2 Optix lenses. As O2 Optix are not approved for overnight wear (a full night's sleep), napping in them for a short period of time is not advisable either, and it can lead to eye-health complications. Napping for any length of time with contacts not designed for such an environment is risky. Choose a lens that is approved for overnight wear and seek guidance from your ECP if this is a requirement for you.

You need 4 box(es) of O2 Optix contacts to last you for 12 months. These amounts pertain to a single eye, so to cover both eyes, double these amounts.

Yes, all contact lenses, including O2 Optix ordered from Lens.com are FDA-approved, genuine lenses manufactured by top contact lens brands such as Bausch + Lomb and Alcon, and backed by a money-back guarantee.

We go above and beyond, by making the experience efficient, easy, and pleasant with 24/7/365 customer service and a money-back guarantee.

If you're wearing O2 Optix for the first time, it can take several days to a couple of weeks for you to adjust to wearing them on a daily basis. Contacts vary from brand to brand in terms of their shape, material, breathability, wetting agents used, and other factors, thus requiring an adjustment period. Rigid/hard lenses can sometimes take longer to adjust to, whereas most contacts in use today employ a soft form of silicone that is typically easy to adjust to.

Unfortunately no, you can't use your eyeglass prescription for O2 Optix lenses. Your eyeglass prescription only has the power part of the contact lens prescription. In addition to the power, the proper base curve (BC) and diameter (DIA) are needed to order contact lenses. Contact lenses come in different sizes and must be fit to your eye by an Optometrist or Ophthalmologist. As a replacement center, we can only sell you contact lenses that you are already wearing successfully. So ultimately eyeglass prescriptions are not the same as a prescription for O2 Optix contacts. See an ECP/optometrist if you're looking for a contact lens prescription and fitting as a first-time-wearer.

Yes, O2 Optix is FDA-approved. The U.S. Food and Drug Administration regulates all contact lenses as prescription medical devices and thus must go through an approval process, after which they can be legally sold in the US (if approved).

Like most contacts, including O2 Optix, they can be worn by teens and potentially pre-teens as well, per the direction of an ECP. In general, there is no fixed minimum age for wearing contacts, as it's a judgment call based on lifestyle habits, budget, and of course your ECP's guidance. Contacts do require care and consistency in usage and maintenance/cleaning and these are the lifestyle factors you should consider when thinking about contacts for a child.

You will know O2 Optix contacts are inside-out if they feel uncomfortable in your eye. An inside-out contact lens will also move too much when you blink, and they may even pop out. Some contacts feature an inside-out mark that can be checked once removed, but this is not the case with all lenses.

Contacts, like O2 Optix are made of hypoallergenic materials, meaning the contacts themselves don't usually cause an allergic reaction. In most cases, what causes an allergic reaction is a buildup of contaminants on the contacts. If you experience redness, watering, and other symptoms of a possible allergic reaction, remove your contacts immediately and consult your ECP.

O2 Optix contacts are typically available to purchase at your nearest brick-and-mortar eyewear store or ECP's office. However, the lowest prices and largest inventory of these lenses can be found online, such as at Lens.com, where greater volumes and lower overhead can translate into significant savings over store-bought contacts.

Like all contact lenses, O2 Optix lenses do expire. The expiration date will be stamped on the box itself or on the aluminum fold of the blister pack in either a YYYY-MM or YYYY-MM-DD format. Typically, the expiration date for contacts is several years after the date of packaging.

O2 Optix contacts have a water content of 33%. The higher the water content in a contact lens, the more oxygen reaches the cornea during lens wear. There are other factors at play however so water content alone isn't enough of a factor to judge a lens' performance for a given person. High water content lenses can feel comfortable initially but may dry out over time, but this is not always the case. So it's good to know about the water content of a lens, but it's not everything. Consult your ECP to find out the best options for you.

Daily disposable contacts cannot be stored and must be discarded at the end of each day. Even if you wear them for only a few hours one day, you still need to discard them after that use and wear a fresh pair of contacts the next day. 

You may keep weekly contacts in multi-purpose contact solution in a tightly closed contact lens case for up to 2 weeks. 

For monthly replacement lenses you may store them in contact solution in a tightly closed contact lens case for up to 30 days.
